Care and Maintenance
Your Earthquake Stereo
Keep the graphic equalizer dry. If it gets wet, wipe it dry immediately. Liquids contain minerals that can corrode electronic circuits. Additionally liquids can cause severe electrical shock.
Use and store the graphic equalizer only in normal temperature environments. Temperature extremes can shorten the life of electronic devices and warp or melt plastic parts.
Handle the graphic equalizer gently and carefully. Dropping it can damage the circuits or cause components to break or become loose. These kind of actions can cause the units to work poorly or improperly.
Keep the graphic equalizer away from dust and dirt, which can cause premature wear of parts.
CAUTION: Earthquake products are capable of generating high sound pressure levels. You should exercise caution when operating these products. Long term exposures to
high levels of sound pressure will cause permanent damage to your hearing. Sound pressure levels exceeding 85dB can be dangerous with constant exposure. Set your audio system to a comfortable loudness level. Earthquake Sound Corporation does not assume liability for damages resulting from the direct use of Earthquake amplifiers or other Earthquake products , and urges users to play their music at moderate listening levels.
